Ku-192 kbps noma ngaphezulu, imiphumela ihlala icacile kakhulu. Uma une-lossless master nganoma yikuphi, uku-encoding i-MP2 kusuka kulo kunciphisa ukudlula okuphindiwe ngokuphelele.

Ingabe ihele lami MKV liyimfihlo ngesikhathi sokukhipha umsindo?

Yebo - imodeli yobumfihlo efanayo njengezo zonke iziguqulo: abasebenzi abahlukanisiwe, akukho kuhlolwa komuntu, ukususwa okuzenzakalelayo ngaphakathi kwemizuzu yokuqedwa. Ifasitela lokugcinwa okuningiliziwe ku /privacy/.
